KIT and testicular germ cell tumor: Acute myeloid leukemia, seminoma/dysgerminoma and sinonasal NK/T-cell lymphoma, neoplasms related to KIT mutations (often in exon 17) [49], at the best of my knowledge have never been described in germline KIT-mutants (curiously, some familial germ-cell tumors revealed somatic KIT mutations [59]).
